“…The use of bamboo as rebar contributes the minimum deformation and crack propagation, but low elastic modulus (Awoyera, et al, 2019). The strength of bamboo reinforced concrete can be improved by adjusting the shape of the bamboo rebar, such as the present of bark and node contribute the higher tensile strength up to 50% (Muhtar, 2021). Another study also shows the presence of notches and clamps can increase the bond-stress and flexural capacity, as well as reducing slip between the bamboo and concrete (Al-Fasih, et al, 2021) (Budi, et al, 2019) (Muhtar, et al, 2019).…”
